2. Description of the Related Art Considering economic growth in developing countries, the development of global supply chain concepts, increasing economic and commercial exchange in all regions, and easing global financial and transport management, e-business Is becoming a business trend. SCM (Supply Chain Manage)
(Ment: supply chain management), it is possible to provide users with highly efficient and high quality products. On the other hand, at the same time, minimizing operating costs has been a key for companies to remain internationally competitive in global markets.

[0003] In conventional material distribution systems, warehouses have primarily played a storage and maintenance role. But,
Under the pressures of fluctuating consumer needs, data complexity and volume, and market competition, the inflow and outflow of goods into and out of warehouse systems must meet market demands for low volume, wide variety and time efficiency. Fast, complicated.

[0004] In various technologies of material distribution, ASRS
(Automated Storage Retrie
The use of a val System is one of the best solutions. However, most ASRS in Taiwan are used in factory material or distribution warehouses. There are not so many types of stored goods, most of which are stored and received in large quantities,
As shipped, the basic operation of the ASRS is very simple.

[0005] The receipt and transportation of goods uses a cargo transport pallet as a basic unit. Thus, there is no need to plan any selection modes for assistance in the material delivery operation. The function of ASRS is mainly storage.

ASR once completed in a material collection and delivery center that requires small quantities, wide variety, high frequency and fast delivery
S is attached, the storage functionality interface (s

ng functional interfaces)
Will have the integration challenge of generating

[0007] ASRS locator design
Planning is the key to solving the above problems, and is also a major factor affecting the operation time and usage frequency of the storage and retrieval device. Therefore, the development of effective locator planning rules when creating ASRS for them on behalf of merchants, and the locator change policy are currently urgent issues.

Before describing the system of the present invention, conventional warehouse systems and their disadvantages will be described.
The consequences of the limitations in conventional systems and the reasons for improving the system for the realization of a virtual hub have been discussed. With these technologies, warehouse systems have advanced through the following generations.

<Initial> In the initial stage, a fixed warehouse person manages a fixed material in a fixed area.

The initial disadvantages are as follows.

(1) The system must be manually updated for operational and maintenance situations. As a result, mistakes can be made or time consuming.

(2) When a person assigned to a specific material rests, no one knows where the person's assigned material is stored.

(3) In selecting materials, an employee needs to determine whether or not the selected material is correct.

(4) In counting materials, it is necessary for an employee to determine whether or not the amount of the material is correct.

(5) Storage status cannot be known until all orders have been manually entered into the system at the end of the day.

(6) It is impossible to control the FIFO (first-in first-out).

(7) It is impossible to know from which material supplier a specific material comes.

(8) Unable to perform a material check until the operation is stopped.

(9) There is no reservation function.

<Current> At present, each locator is controlled. The supplies are randomly stored, numbered locators for the system that generates the selection list.

Although some problems of the above system have been solved, there are still the following problems. The disadvantages at present are as follows.

(1) In selecting materials, it is still necessary for an employee to determine whether or not the selected material is correct.

(2) In counting materials, it is still necessary for an employee to determine whether or not the amount of the material is correct.

(3) Storage status cannot be known until all orders have been manually entered into the system at the end of the day.

(4) Until the operation is stopped, the material check cannot be executed.

(5) There is a time delay in the reservation function.

As the modern economy expands globally and e-business becomes prevalent, the distribution function becomes increasingly important. Modern commercial centers that integrate “material distribution, financial distribution, financial distribution and information distribution” will become mainstream in the future. Completed warehousing systems are increasingly key to business management success in the era of global competition. The warehouse system center is the main point of the goods distribution industry. If decision efficiency can be improved, the business can maintain its competitive advantage.

[0028]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the catalog data is replaced with the actual catalog data without any time delay by using a bar code online operation by an RF (radio frequency) device or a bar code machine. It can be seen on the website as exactly the same. According to the present invention, the storage state of the owner of each vendor can be managed by managing the barcode.

Thus, it is highly desirable to provide a warehouse management model that uses a warehouse management system and to perform complete bar code management. Ingress or egress to or from the warehouse center is immediately updated in the inventory data by radio frequency (RF) equipment. This new way of managing
The following functions that the conventional warehouse could not achieve can be provided.

(1) Periodic material checks can be performed at any time without stopping any activity or order processing.

(2) Radio frequency (RF) devices replace paperwork, resulting in paperless processing.

(3) Information about the barcode, such as its locator, supply carton, supply box, and cargo carrier, can be immediately known by simply scanning the barcode.

(4) Conventional management based on the total number of materials can be improved to management based on boxes or packs.

(5) The system can execute FIFO control.

(6) It is not necessary to stop the operation of the locator for selecting the material. The system can update the data immediately while the box moves.

(7) The entry / exit time and entry / exit amount of specific materials and the number of operating personnel are recorded in the system, and bin card management can be achieved.

(8) The time during which the material in each carton is not selected and is not moving can be calculated. This information is used to process materials with low usage rates.

The method of the present invention can be applied to WIP (Work In)

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings so that the present invention can be fully understood. However, the present invention
The present invention is not limited to the following description, and can be appropriately improved by those skilled in the art.

The specification discloses a warehouse system with optimal management procedures in response to recently proposed BPR (Business Method Reengineering) and ERP (Enterprise Resource Planning). The aim is to redesign the warehouse operating procedures to increase the production while reducing the cost of the configuration operation.

Since the present invention is implemented in a warehouse system, inventory management, locator transfer,
Material distribution operation, material selection operation, and SFCS (Sho
The pFloor Control System automatically collects data using an automatic data collection method. Various types of optical and electronic scanning devices or bar code machines are used to read the data. The obtained data is updated in the system in real time, so that problems due to time delay can be avoided.

A preferred embodiment is described below to clarify how the disclosed method is implemented. With a warehouse management system, supplies from different vendors are consolidated for easy management and given to assembly line managers.

Prior to the detailed description of the present invention, first, an operation procedure of the present invention and a selection method for determining a product hierarchy will be described.

Prior to the shipment of any product by the manufacturer, the ASN (Advanced Shipping No.)
ticket: advance transportation notice) is first sent out.
The BC (barcode) of each box of supplies is scanned and its quantity is checked according to the Advance Shipment Notice (ASN). The barcode (BC) is used as an ID for each material.

However, not all vendors can meet this requirement. in this case,
Those who do not have an advance transportation notice (ASN) will be provided with an advance transportation notice (ASN) and will receive a bar code (BC)
Barcode (BC) on any products not marked with
Is given.

After scanning the barcode (BC), according to the scanned PO (Product Order), the system sums the number of different commodities. The number scanned is then PL (Pick
ing List: selection list).

FIG. 1 is a diagram showing a hierarchical relation of product selection determined by the warehouse management system of the present invention.
It is used to define the selected unit in storage.

For the data level analysis provided by the vendor, the top level is the advance transportation notice (AS
N) or so-called cargo 10. At the bottom of the cargo are several cargo carriers 20. Each freight carrier 20 is arranged with a plurality of material cartons 30.

Each material carton 30 has the same PO (Pro
Duct Order (product order) contains the same type of material. Each supply carton 30 includes a plurality of supply boxes 40 in which a plurality of supply items 50 are stored.

The bar code (BC) label is attached to each unit as its ID. The above-mentioned barcodes (BC) must be data associated with each other to form an ASN or include a standard shipping list. The warehouse management system of the present invention provides a bin card that converts an ID consisting of a barcode (BC) into a text description. Thus, the operator can obtain information related to the supplies during the operation.

The above input data is RF (radio frequency)
It is obtained by scanning each barcode (BC) using a scanner. After a box of supplies is placed on a shelf in the warehouse, the barcode (BC) becomes the ID of the box.

Information such as the locator in which the box is placed, the inspection amount, the person who inspected them, the time of arrival of the box, and the company to which the box belongs is recorded in the ID, and the warehouse management system centralizes its management. be able to.

Referring to FIG. 2, a hierarchical relationship diagram will be described below. Count all supplies and use each barcode (BC)
, The RF scanner sends the data to the warehouse management system in real time. At that moment, the warehouse management system generates hierarchical data as shown in FIG.

Then, a plurality of RTs (Receiving
g Ticket: received ticket 110 is PL (Pi
cking list (selection list) 100. In the same receipt ticket (RT) 110, a material carton 40 having the same capacity as the material item 50 is provided in SO (Sto
ring Order (storage order) 120. The storage order (SO) 120 stores a plurality of locator addresses 130. Thus, the necessary material carton ID 150 and material item ID 150 can be found from the barcode (BC).

With the complete bar code (BC) management of the warehouse, the ingress or egress of goods is immediately updated through the RF scanner, real-time operation is achieved. The distribution of supplies is a very complex operation, as different needs are met in different ways of selection in the selection of supplies.

Although not particularly described below, taking in and out of goods, moving, and scanning of a bar code (BC) by the RF scanner are performed by personnel. Information scanned by the RF scanner is managed by the management function of the warehouse management system.

As shown in FIG. 3, the warehouse management system
Provides multiple modules and management functions for material distribution and selection operations. Warehouse management system 200
Are the simulation module 210, the reservation module 212, the previous reservation module 214, the commission module 2
16 and a deduction module 218. Five modules are prepared for the material distribution operation 230. The aim is to solve the problem of normal material distribution operations.

The above five modules will be described in detail below.

(1) Simulation module 21
0: This module provides a simulation function. This function prepares materials required for an assembly line in the future according to a predetermined production schedule by calculation of the warehouse management system 200.

(2) Reservation module 212: This module provides a reservation function. This function reserves the material calculated by the simulation module 210 and prevents the reserved material from being used by other units.

(3) Pre-reservation module 214: This module provides a pre-reservation function. Reservation module 21
Because 2 only reserves the total amount of supplies, not individual cartons, supplies may be short due to material deterioration. At this point, the pre-booking module 214 automatically determines a shortage of supplies and executes a pre-booking. Once the shortage is received, the warehouse management system 200 then reserves the material directly.

(4) Commissioning module 216: This module provides a commissioning function. This function entrusts reserved supplies to each supply carton for selection by the selected personnel.

(5) Deduction module 218: This module provides a deduction function. This function subtracts the number of selected supplies from the number of reserved supplies.

The first area 310 includes a first area 310 such as an O.T.O.G. (surface mounting technology), the second area 312 such as a hand-plugging area, and the third area 314 such as a system assembly area.

The selection area is set according to the usage rate, for example,
First KC (Kitting) like motherboard KC

340, and a component area 350.

FIG. 5 is a flowchart showing the flow of the management operation of the disclosed workplace control system (SFCS). First, a storage area, a selection area, and a WIP management area are established in the SFCS (step 400).

Thereafter, the storage area is divided into a plurality of different areas (step 410). The selected area is divided into an assembly center (KC) having a high usage rate and an assembly center (KC) having a low usage rate (step 41).
2). Further, the WIP management area is divided into a plurality of assembly lines (step 414). After these divisions, S
The FCS can perform material selection, distribution and production.

Reservation by WO (Work Order: work order) and client KO (Kit O
According to (rder: assembly order), the SFCS moves each entrusted material carton from the storage area to the selected area (step 420). The supplies in the selected area are then
It is sent to the IP management area (step 430).

Materials are supplied to the assembly center (K
C) or from a low utilization assembly center (KC). Assembly center with low usage rate (KC)
Will first use the remaining material, or
The supplies carton can be opened and the supplies broken down into components for use (step 440). The material having the highest priority for use can be immediately used for production (step 450). The supplies distributed to the components are provided to the research center, the maintenance center, and the units requiring the components (step 452).

On the other hand, a small work order (small work order)
Only when all the supplies can be prepared by WO), the assembly center (KC) with a high usage rate distributes the supplies (step 442). In other words, a high utilization assembly center (KC) does not distribute supplies to the WIP management area until all the supplies needed in the WO are ready. In step 450, materials on the assembly line are used to create a product.

Materials not used in the WIP management area are:
It can be returned to the high utilization assembly center (KC) or the low utilization assembly center (KC) (step 460).

Unused material returned to the high utilization assembly center (KC) must be periodically returned to the storage area for future use (step 470). Unused material returned to the low utilization assembly center (KC) is maintained by the assembly center (KC) (step 472).

The system automatically determines if unused materials are held for too long and whether they have become dead materials (hereinafter simply referred to as dead materials). (Step 480).

If the material is dead (step 4
80: YES), they are returned to the reject store (OBS) (step 490). When the client needs to use a material that has not been used yet (step 480: N
O) Return to the process of step 440 to execute the use and production of the material at the assembly center (KC) with a low usage rate.

The above-mentioned high utilization rate of the assembly center (K
C) For example, the motherboard assembly center (motherboard KC) 320 stores high utilization materials to save space. Even if the material has a slow flow rate, it is returned to the storage area and the assembly center (KC)
Prevent excessive storage of

SMT area 310, manual connection area 312,
And the system assembly area 314 has three different storage areas to facilitate the material dispensing operation. The valuables room (SR) stores expensive materials such as a CPU and a DRAM, for example. Thus, it performs a completely different material distribution operation, with a person assigned to the choice of material.

If the system generates a selection list (PL) for the valuables room (SR), the assigned personnel can select the goods by the RF scanner and then use it to select the goods. Since the valuables room (SR) stores valuable goods, the cargo freight carriers and boxes are cleared to the valuables room (SR) after selection to avoid theft. Only when the assigned personnel come to pick up the supplies, they are moved to the locator for the distribution of goods and to the assembly line.

The locator transfer usually results from a request for knitting of the locator. The warehouse management system first looks for locators that contain less than a predetermined amount of cartons and combines them to form a list of locators for transport. According to the list, the material carton of the locator is moved from the unit cargo area (UL) to the mini cargo area (ML), or the material remaining in the carton of the mini cargo area (ML) is combined with a new material carton. Moved to Small Mini Cargo Zone (SML).

The warehouse management system further provides an SKC (System Assembly Center). However, some selection stations may have ASRS (Au) because the size of the system supplies is too large to be stacked online in a selection or assembly center (KC).
tomated Storage Retrieval
System (automatic storage and retrieval system)
(tlet), it is designed to be a set (see FIG. 6).

FIG. 6 shows a storage area and an assembly center (K
3 shows a preferred embodiment of the invention, showing the relationship between C).

ASRS has different assembly orders (KO)
, 512 and 5 according to
The goods are transferred to 14. This procedure is performed using an automatic belt if space is available. Then, at the selection station, the selection personnel scans the barcode (BC) on the supplies carton 40 to determine the quantity to select.

[0108] The remaining material is returned to the storage area of the ASRS ML500. If all the assembly orders (KO) have been processed, the storage in the system assembly center (SKC) must be exhausted.

The only problem with this method is that it is not convenient for small and frequent selections because the ASRS and the selection station can be overloaded. If this production style is required, a motherboard assembly center (motherboard KC) can be used.

Another issue is two assembly orders (KO)
If the same carton is commissioned at the same time, one of them may not be able to get supplies in time.

Further exceptions are the System Assembly Center (S
It is a valuables room (SR) in KC). The system assembly center (SKC) is divided into the following two types. One is a locator for the selection station and the other is a valuables room (SR).

One assembly order (KO) of the warehouse management system generates two selection lists (PL). One is a selection station and the other is a valuables room (S
R).

Thus, the ASRS unit cargo area (U
L) and ASRS ML (ASRS mini cargo area)
Is divided into two regions. If there is a commissioned system assembly order (KO), the warehouse management system commissions the ID of each material carton.

At the same time, the warehousing management system will provide the selected stations (UL) and mini-loading zones (ML) with the selected stations to obtain supplies (in cartons), respectively,
Generate two assembly orders (KO). Selection list of selected station (PL) when supply operation starts
Also starts the selection operation. One selection list (PL) corresponds to multiple assembly orders (KOs), and only one RF device is assigned to each assembly order (KO) for material selection. Only one selection list (PL) can be processed at a time.

The surplus material from the selection at the selection station is returned by the assigned personnel to the ASRS Unit Load Zone (ASRS ML) in addition to the material carton. For each selected station, the system assigns a locator ID. Which supply station supplies (or selects) the material is determined by the material supply personnel (or selection personnel).

Referring to FIG. 7, at the assembly center (KC) 552 in the selection area 550, the goods are PW (Pr).
product warehouses (product warehouses) 560, 562 and 564. Each product warehouse (PW) has multiple assembly lines 570,
572 and 574. Since each assembly line has a locator, the warehouse management system manages each product warehouse (PW). Work orders (WOs) are individually listed for each assembly line. Materials on different assembly lines cannot be shared.

[0117] A safe storage quantity is provided for each material. If the material is stored under its safe stock, the warehouse management system will automatically replenish the material. This material replenishment procedure is called a backflush operation.

The backflush operation will be described below with reference to FIG.

First, when a material is moved, the ID on the material carton is scanned (step 600). Based on the scan results, the system automatically deducts the quantity of the material (step 610).

[0120] The system then checks whether the quantity in the product warehouse (PW) is below a safe stock (step 620). If it is below the safe stock (step 620: YES), a location transfer request list is generated and given to the assembly center (KC) for material selection (step 630). The goods selected at the assembly center (KC) are put into a goods carton and transferred to a PW locator (product warehouse locator) (step 640).

If the amount of the material is not lower than the safe storage amount (step 620: NO), the process directly proceeds to step 650. After manufacturing is completed, the ID is scanned (step 650). Product supplies are deducted from the inventory and transferred to the product (step 660). The generation cycle time of the location transfer request list is set by the warehouse management system.

It is clear that the invention detailed above can be modified in various ways. Such variations do not depart from the scope of the technical idea of the present invention, and modifications obvious to those skilled in the art are included in the claims.
